read_normalized_at() [3/4]

MAYAFLUX_API double MayaFlux::Kakshya::read_normalized_at	(	const DataVariant &	v,
		Portal::Graphics::ImageFormat	format,
		const std::optional< DataDimension::ValueRange > &	range,
		size_t	elem_index
	)

Read one element as a normalised double, with optional range remapping.

Same as read_normalized_at, but if range is provided, the value is linearly remapped from [range.min, range.max] to [0.0, 1.0]. Values outside the range are clamped to 0.0 or 1.0.

Parameters

v	Source variant.
format	Pixel format governing the uint16 interpretation.
range	Optional value range for remapping.
elem_index	Element index. Returns 0.0 when out of range.
